GRAIN-CAR DOOR.

Application filed March 8, 1906. Serial No. 304,825.

To @ZZ whom it may concern:

Beit known that we, ROY J. COOK and HILLMAN H. HARvEY, citizens of theUnited States, residing inl Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Grain-Car Doors,of which the following is a speciiication.

Our invention relates to improvements in doors for grain-cars.

The obj ect of our invention is to provide a grain-car door of asilnple, eflicient, strong,

Vemploy to practically accomplish this object and durable constructioncapable of being easily and conveniently released or opened. Ourinvention consists vin the means We or result-that is to-say, itconsists, in connection with the main' door upon which our lrelease orsupplemental door is ordinarily mounted having an opening to receive therelease-door and provided with strips or keepers at the ends thereofadapted to engage and hold the outer ends of the release-door in place,while permitting them to move toward each other to free themselves fromsuch overhanging strips or keepers, of a releasedoor comprising twosections or members hinged together at their meeting ends and connectedat their upper edges by sliding two-way hinges to the main door, one ofthe hinged sections of the release-door having an outer projectinghandle member overlapping the hinge connecting the two sections and theother section being provided with a fastening and releasing deviceengaging said projecting handle member, whereby whenr the handle memberis unfastened or released `the two sections of the release-door may`swing outward at their middle until the opposite ends are withdrawn orretracted from the strips or' keepers on the main door, and then therelease-door may be swung upward against the main door or part uponwhich it is mounted, the two-way hinge which connects the release-doorwith the y main door permitting first the outward or 5 in shown anddescribed.`

In the accompanying drawings, forming a part of this Speciiication,Figure lis a side elevation of a grain-car door embodying our inventionandshowing a portion of the car to which it is applied. Fig. 2 is aview, partly in vertical longitudinal section and showing the door inelevation from the inside. Fig. 3 is an enlarged horizontal detailsection on line 3 3 of Fig. 1. Fig. 4 is a similar view showing thegrain-door partly opened and its opposite ends almost retracted orwithdrawn from the strips orkeepers on the main door. gig. 5 is a detailvertical section on line 5 5 of In the drawings, Arepresents a vortionof a grain-car having an opening therein yclosed by the main door B,which is or may be of any suitable or desired construction known tothose skilled in the art. The door is preferably a vertically -slidingand inwardly-swinging one, moving up and down on the guides or rods Band having metallic guides or loops b attached to the door to engage therods B.

The main door B has an opening C therein, which is closed' by thesupplemental or release door D, and the main door is also .provided withguide strips or keepers B2, which overlap and engage the ends of thereleasedoor when the-same is closed and'hold the same in position.

The release-door D 'comprises two hinge sections or members d d,connected together at their meeting ends by a hinge d', the axis orpintle d2 of which is upright. The sections or membersd d are preferablymade of equal lengths, so that the hinge d will come at the middle ofthe release-door, although the sections may be made of unequal length,if desired. Each of the sections d ofthe release-door is hinged at itsupper edge and near its outer end to the main door B by a two-way hingeF, preferably comprising a pin or bolt f, having an upright arm fiitting in a strapfz, secured to the main door, and a horizontal arm f3,iitting in the hinge-strap f4, secured to the grain-door section d, thestrap f4 being adapted to slide on the arm f3 to accommodate the two-wayswinging movements-of the door-section. The rightangle hinge-bolt f hasat one end a head f5 and at its other or horizontal end a washerPatented Jan. 8, 1907. v

f and Cotter-pin f7 for preventing the re- I IIO.

jecting beyond the hinge d d2, which connects the meeting ends of thedoor-sections d yd. This handle member d3 is furnished with a handle d4and with a slot d5' to receive the fastening and releasing device d,which is secured `to thefother or companion door-section d, thisreleasing device consisting, preierably, oi a bolt with a right-anglearm or handle d2 for turning the same.

In operation, the door being` in its closed position, .as represented inFigs. l and 3, the lfastening or releasing device d is simply :turned tobring its arm (Z7 parallel with the :slot di in the handle member d3 andthen lthe pressure of the grain against the door from the `inside swingsthe door outward, .the .two sections d d turning on the hinge, whichconnects their meeting ends, and also on the upright arms of the hingeF, which .connects the release-door with the main door, the release-doorbeing thus pushed or pulled outward until its opposite .ends areretracted or withdrawn from the keepers, flanges, or strips B2 on themain door, the hinge-straps f4 sliding on the hori- .zontal arm f 2 ofthe two-way hinge to permit this, and then the release-door may be swungvertically `upward against the main door, the sliding of the members ofthe two-way hinges F F then permitting the two sections of therelease-door to resume their normal or straight position.

The release-door D serves when opened to relieve vthe pressure of thegrain against the main door or grain-door pro-per, B, and thus enablesit to be easily and convenientl)7 raised. At the same :time by our novelconstruction and combination of parts the release-door is firmly andsecurely held in its .closed position and can also be very easilyreleased 'by simply turning the fastener (ZG.
